RLC Circuit: Find Missing Component - Inductor?

AI Thread Summary
The discussion revolves around determining the missing component in an RLC circuit with an impedance of 192 and a phase angle of -75 degrees. Participants suggest that the missing component could be an inductor or a capacitor, with a focus on the inductor. The reasoning provided highlights that the voltage across an inductor leads the current by 90 degrees, which may explain the negative phase angle. The conversation emphasizes the relationship between impedance, phase angle, and circuit components. Ultimately, the consensus leans towards the possibility of an inductor being the missing element in the circuit.

1. if a impedance at 192 ,phase angle -75, resistor 49.7, wat missing in this circuit? A inductor or capacitor?
Can it be a inductor?

maybe :rolleyes:

give reasons! :wink:
 
Inductor since The instantaneous voltage across the inductor VL leads the instantaneous current by 90 degrees. Is that the reason?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
